Let's divide 73124209 by 780
We want to divide 73124209 by 780.

Moving on to step 1:
780 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 780

Let's proceed to step 2:
73 divided by 780 is 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 780

Going ahead to step 3:
780 can be fit into 731 0 times, resulting in a remainder of 731.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 731 and we're left with 731.
Include the next digit (2) from the dividend after 731, then repeat: 7312 / 780

On to step 4:
When dividing 7312 by 780, we get 9 with a remainder of 292.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 7020 from 7312 leaves us with 292.
Fetch the next digit (4) from the dividend, attach it to 292 and continue: 2924 / 780

On to step 5:
780 can be fit into 2924 3 times, resulting in a remainder of 584.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Deduct 2340 from 2924 and we're left with 584.
Bring next digit (2) of the dividend behind the 584 and repeat the process: 5842 / 780

On to step 6:
The number 780 fits into 5842 7 times, leaving a remainder of 382.
Record the quotient 7 as the next digit in the result. 
Result so far: 937.0
Deduct 5460 from 5842 and we're left with 382.
Include the next digit (0) from the dividend after 382, then repeat: 3820 / 780

On to step 7:
If we divide 3820 by 780, we get 4 and a remainder of 700.
Write down 4 as next digit of the result. 
Result so far: 9374.0
If we subtract 3120 from 3820, we get 700.
Bring next digit (9) of the dividend behind the 700 and repeat the process: 7009 / 780

Step 8:
The number 780 fits into 7009 8 times, leaving a remainder of 769.
Use 8 as the next digit of our solution. 
Result so far: 93748.0
If we take 6240 away from 7009, we end up with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Let's proceed to step 9:
The number 780 fits into 7690 9 times, leaving a remainder of 670.
Write down 9 as next digit of the result. 
Result so far: 93748.9
The remainder is 670 after subtracting 7020 from 7690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 10:
6700 divided by 780 is 8 with a remainder of 460.
Use 8 as the next digit of our solution. 
Result so far: 93748.98
Subtract 6240 from 6700 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 11:
The number 780 fits into 4600 5 times, leaving a remainder of 700.
Record the quotient 5 as the next digit in the result. 
Result so far: 93748.985
If we take 3900 away from 4600, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 12:
If we divide 7000 by 780, we get 8 and a remainder of 760.
The number 8 becomes the next digit in our result. 
Result so far: 93748.9858
If we subtract 6240 from 7000, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 13:
780 can be fit into 7600 9 times, resulting in a remainder of 580.
Use 9 as the next digit of our solution. 
Result so far: 93748.98589
Subtract 7020 from 7600 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 14:
780 can be fit into 5800 7 times, resulting in a remainder of 340.
Write down 7 as next digit of the result. 
Result so far: 93748.985897
Deduct 5460 from 5800 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 15:
780 goes into 3400 4 times with a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 93748.9858974
Deduct 3120 from 3400 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 16:
When dividing 2800 by 780, we get 3 with a remainder of 460.
Use 3 as the next digit of our solution. 
Result so far: 93748.98589743
Subtracting 2340 from 2800 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Our division results in 93748.98589743 with a remaining 4.6e-07.
